Maintenance of a legacy system for enterprises could prove to be extremely difficult and expensive and it may also quickly exceed the cost of a new higher quality system. In such cases enterprises resort to discontinue with the existing legacy systems and find reengineering the system to be prudent. We at TVS Infotech, in re-engineering the whole system, study and form a description of the existing system’s workings (requirements/reverse-engineering phase). Next the requirements are updated to meet the current business needs with the

necessary tweaking done.,. In the last phase, the system is forward-engineered for a smooth rollout on new technology platform that meets the exact business process.

Our application migration & re-engineering services include:

• Migration Assessment: Application rationalization, inventory identification, migration strategy definition, migration roadmap definition, optional POC
• Application Porting: Port an application to a new OS or DB
• Application Upgrade (within same operating environment): Language version, OS version, database version, IDE/tools version, product scripting
• Application Re-Engineering for new/improved business functionality and operation: Reverse engineering, POC (recommended), partial or full redevelopment, warranty support, optional maintenance support
• Data Migration: Schema translation, data migration, data cleansing
• Technology Migration: Language migration, OS migration, database migration, user interface migration
